A hand held, home use, device for treatment of skin, comprising: a housing exhibiting an opening therein and forming an air cavity when the opening is placed in contact with the skin; an incandescent type bulb secured within the housing and arranged to irradiate the skin with infra-red radiation and heat air within the formed air cavity, the incandescent type bulb exhibiting a filament; and a control and driving circuitry in electrical communication with the incandescent type bulb and operative to output a train of pulses exhibiting an on time when current is driven through the filament and an off time when current is not driven through the filament, the off time greater than or equal to the on time, the off time being of a duration such that the infra-red radiation irradiating the skin falls, during the off time, to no less than 25% of its maximum value. |
